Application filed November 21, 1914. Serial No. 873,308.

To all whom it may concern Be it known that I, LARS AUGUST PETER- SON, acitizen of the Kingdom of Sweden, residing at Vikingagatan 9, in thecity of Stockholm, Sweden, have invented a new Means for Fixing a /Vheelor the like on Its Shaft, of which the following is a specification.

My invention relates to means for fixing a wheel or the like on itsshaft and is preferably intended to be used in automobiles and the likewhere a pinion or the like fixed on a swingable and telescoping shaft isintended to engage any one of a series of conaxial gears or the like. Inhitherto known constructions of such change speed gearings said pinionis either integral with its shaft or fixed thereon by means of a nutscrewed on the projecting end of the shaft. In both instances it isdifficult or tedious to change (take off and put on) the pinion, as thiscan only be done by screwing apart a great deal of the mechanism. If theteeth of the conaxial gears are directed inwardly it is also diflicultto ascertain whether the means intended to prevent unscrewing of the nutis in proper order, as this means is then hidden in the hollow conusformed by said gears. In order to avoid all these difficulties, I fixthe pinion by means of a bolt passed through a central bore-hole in theshaft and tightened by a nut screwed on the top of the bolt whichprojects at the other and of the shaft, the head of the bolt being sunkinto the pinion so as to not projectoutside of the rear end of thelatter.

On the annexed drawing, which shows an example, a is a swingable andreciprocable support in which the shaft 7) is rotatable in rollerbearings r. The front end of this shaft has the shape of a fork g, whichis a member of a universal joint Z. The rear conical end of the shafthas segmental slots and the wheel has straight slots, for suitable keys,and the shaft has a central longitudinal bore for the bolt f, whichlooks the pinion c on the shaft. The rear end of the pinion has anexcavation for the head of the bolt. The nut m can be locked by a splitpin ;0 or the like.

In assembling the parts the shaft 6 is passed from before into itsbearings and the bolt f with the pinion passed thereon is passed frombehind into the shaft. hen the shaft is fully inserted, the segmentalkeys is are placed in their slots and the pinion is passed on the shaftand the bolt is fully shoved in and locked by screwing on and tighteningthe nut m, which in its turn is locked by the split pin 7). Lastly theuniversal joint is assembled. The taking apart is effected in the sameway but in the reverse order.

This .construction has the following advantages: 1. The universal jointis easier to manufacture correctly as the portion thereof intended to berigidly connected to the shaft 6 is integral with it. 2. The pinion 0can be changed in a few minutes. 3. hen the lid of the casing of thechange speed gearing is removed you can at once control the lockingmeans for the pinion, as the nut m is then fully uncovered.

What I claim is:

1. In combination with a wheel and its forked shaft having alongitudinal bore, means for securing the wheel at the end of said shaftcomprising a bolt passed through the longitudinal bore of said shaft anda nut between the prongs of the shaft fork for locking said bolt, thehead of said bolt engaging the wheel and the nut engaging the end ofsaid shaft, substantially as described and for the purpose set forth.

2. A means for securing a wheel on its shaft comprising in combination ashaft forked at its front end and having a longitudinal bore, a supportfor said shaft, a pinion at the rear end of said shaft, a bolt in thelongitudinal bore of the shaft for looking with its head said pinion onsaid. shaft, a nut on said bolt between the fork of said shaft forlocking said bolt, and means for locking said nut, substantially asdescribed and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LARS AUGUST PETERSON.
